When a ball is thrown vertically upwards, its velocity goes on decreasing. What happens to its potential energy as its velocity becomes zero ?
If the velocity an object increases 4 times, its kinetic energy increases
For a body thrown vertically upwards, its direction of motion changes at the point where its total mechanical energy is
The velocity of a body is doubled. What happens to its momentum?
Statement 1 : An object thrown vertically up with a velocity u reaches the maximum height h after T seconds. At a time 2T seconds its velocity becomes zero. Statement 2: An object thrown vertically up with a velocity comes back to its initial position with same magnitude of velocity but in opposite direction.
A body of mass 2 kg is thrown vertically upwards with an initial velocity of 20 m/s. What will be its potential energy at the end of 2 s ? (Assume g = 10 m//s^(2) ).
A ball is thrown vertically upwards. Which quantity remains constant among, speed, kinetic energy, velocity and acceleration?
